WILLIAM G. MITCHELL, OF NEW YORK, N. Y.

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 232,743, dated September 28, 1880. Application led April 14, 1880. (No model.)

To all whom it may concern Be it known that l, WILLIAM G. MITCHELL, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Gar-Axle Lubricators, of which the following is a specification.

This invention relates to lubricators for the journals of railway-car axles; and it consists in certain novel combinations of parts, hereinafter fully described, and pointed out in the claims.

This invention is illustrated in the accompanying drawings, in which Figure l shows the lubricator in vertical longitudinal section applied to a journal. Fig. 2 is an end view thereof, partly in section.4 Fig. 3 is a plan or top view of the same, partly broken away.

Similar letters indicate corresponding parts.

The letter A designates the box for receiving the oil or other lubricating material, and B thejournal of a car-axle, extending into the box in the usual manner.

The principal features of my lubricator, which rests on the bottom of the box A, are two pivoted frames, C C, a wiper-roller, D, side pads, E E, and an end pad, F. With the two frames G C is combined a spring, f, which acts thereon with a tendency to move the upper portions or ends thereof-namely, those portions which hug the journal B-toward each other, so that the frames readily conform or adapt them selves to the journal. The action of the spring f, however, is limited by means of stops g, (see Fig. 2,)

so that the frames are kept in proper relation to each other when the whole is removed from the box A. The stops g are integral with the frames C C, and in practice the same are so arranged as to permit the frames C O to take a position in which they become spread or expanded against the action of the sprin g f when the lubricator is applied to the journal, and, if desired, the stops may be made adjustable. The spring f may be a spiral or a flat spring, and may be arranged on any suitable part of the pvoted frames C C.

The roller D is mounted on a spindle, L, which has its bearings in the end parts of the frames C O, and thus not only serves to carry the roller, but also forms the pivots for connectin g the frames. The diameter of the wiperroller D is reduced between the ends thereof, and to this reduced part are fastened the wipers l. These wipers consist ot' flexible strips radiating from the roller D, and when light oil is used I prefer to make the wipers of hogs bristles, while for heavy oil I use strips of metal. If desired, the strips composing the wipers l may be covered with chamois or other similar material. The largest diameter of the wiper-roller D is such that when the lubricator is applied to a journal that part of the roller bears against thejournal. l

The side pads, E E, consist of strips of felt or other absorbent material, and are attached to the pivoted frames C G by stitches or other suitable means, their arrangement being such that, like the wiper-roller D, they bear against the journal.

The end pad, F, is attached at its opposite ends to the side pads, E E, or to the pivoted frames C C, by stitches or other suitable means, and when the lubricator is applied to use the end pad projects into the opening through which the journal B enters the box A, while it hugs the journal at that point. By fastening the end pad, F, only at its extremities it does not interfere with the motion of the pivoted frames C C.

By the contact of the wiper-roller D with the journal said roller is caused to revolve, and in this motion thereof the oil is taken up from the bottoni of the box and applied to the journal by the wipers, while the oil thus applied to the journal is absorbed and distributed by the side pads, E E. By the end pads, F, the oil is absorbed and prevented from escaping through the journal-opening of the box, so that no waste takes place.

ln some cases I combine with the pivoted frames U G screens J J, to prevent the spattering of the oil by the wipers.

I am aware that itis not new to use in alubricator two pivoted frames; neither is it new l to use a wiperroller, and I do not claim such features, broadly; but

What I claim as new, and desire to secure by Letters Patent, is-

l. In a car-axle lubricator, the combination of two pivoted frames, a wiper-roller, a spindle carrying such roller and forming the pivots of the frames, and side pads attache-d to the IOO frames, both the Wiper-rollers and. the side the journal, substantially as shown and. depads being adapted to bear against the jourscribed, for the purpose set forth. nal, substantially as shown and described, for In testimony whereof I have hereunto set the purpose set forth. my hand in the presence of two subscribing 5 2.
